# This file is used to automatically generate bionic's the system calls stubs.
#
# Each non comment line has the following format:
#
# return_type func_name[:syscall_name[:call_id]]([parameter_list]) (1|-1|"stub")
#
# Note that:
# - syscall_name corresponds to the name of the syscall, which may differ from
# the exported function name (example: the exit syscall is implemented by the _exit()
# function, which is not the same as the standard C exit() function which calls it)
# The call_id parameter, given that func_name and syscall_name have
# been provided, allows the user to specify dispatch style syscalls.
# For example, socket() syscall on i386 actually becomes:
# socketcall(__NR_socket, 1, *(rest of args on stack)).
#
# - each parameter type is assumed to be stored on 32 bits, there is no plan to support
# 64-bit architectures at the moment
#
# - the final field can be "1", meaning: generate a stub for each architecture,
# taking the constants from the kernel header files.
#
# - the final field can be "stub" meaning: do not generate any stubs ---
# in this case, a hand-written custom stub must be provided.
# TODO: replace this with something like "custom" or "none", or remove
# it entirely.
#
# - the final field can be a three-element list of 1s and -1 meaning:
# this system call is only available on some of the architectures (1),
# and no stub should be generated for those architectures marked with -1.
# the order is arm,x86,mips.
# TODO: replace this with something more readable like "-arm,-mips" (meaning x86 only).
#
# This file is processed by a python script named gensyscalls.py.
